Range Delay time = 16 ns to 250 s Event count = 1 to 10
7
Minimum time between arm (A Event)
and trigger (B Event), typi cal
2 ns from the end of the time period to
the B trigger event
2 ns between the A trigger event and the
first B trigger event
Minimum pulse width, typical — B event width ≥1ns
Maximum frequency, typical — B event frequency ≤500 MHz
